First long trip in the new EcoDiesel, cruise set at 112kmh (70mph) for the trip, had a few short sections of 100kmh (60mph).
My truck is a 2020 limited with 3.92 rear end. Never downshifted once on any hills and is just happy chugging along.

You can see the range until empty and overall average in the photo. So far loving the diesel over my old Hemi.

Nice, my best was just over 27mpg hand calculated on a 1500km trip.

It will be interesting to see what your hand calculation reveals. I babied mine (3.21 rear gears) for a full tank to see how well it would do, dash readout showed 29.3 MPG, actual was 24.9 MPG. That was 50/50 highway/city. Mine turns 1500 RPM @ 65 MPH.
.
It almost seems as though driving the 2020 Ecodiesel to achieve best fuel economy confuses the on-board fuel economy meter algorithms, at least when there's a healthy amount of city driving on the tank..

I'll do a hand calculation on the return leg for the overall. Either way I'm very pleased with the mileage.

Yours being that far off makes me think the pump clicked off late or early on one of the fill ups. Most hand calculations I've seen are within 1 MPG or so.

Perhaps, although so far all fill-ups have been at the exact same pump, and I follow the TFL Truck method - let the pump's auto-shut-off do it's thing, wait 30 seconds, top it off. Also, the next tank was also 50/50 city/hwy, that one had a dash readout of 27.0 MPG, actual (hand calc) was 25.7 MPG.
.
One thing that possibly could be affecting my fuel economy calcs so far is that I have only 1,500 miles on the odo, so the engine is still a little tight and breaking in.
.
Separate question, how is everyone else's 2020 Ecodiesel doing so far WRT oil consumption? At 1,500 miles, mine hasn't used a drop of oil. No towing yet, but a few short hauls with 1,000 lbs of retaining-wall blocks in the bed.

I checked mine before I left and it was full. Not many miles on mine either yet.

I'm at 24.4 right now, mixed city/highway mostly city. Less than 1,000 miles so not at all unhappy with my current mileage. Haven't checked my oil yet, wasn't aware that was an issue. Now, my '69 Alfa GT, that car could go through oil like no ones business.

I'll check the oil once I finish my coffee. :)

Oil level is fine. Would be rather disappointed if it wasn't.

Only seen these trucks with either miles and mpg or KM and l/100 readings never both at the same time as in OP picture.

3.92, 4x4, 1200 miles on the odometer.
25 MPG combined (20 miles each way to work daily) at 70 mph, and 27 MPG on a 650 mile road trip at 80 mph. These numbers are based off the computer.

I just took my first day trip in our new EcoRam (Bighorn crew, 4x4 North, 3.92), about 120 miles > drove around our hometown > 120 miles home. Cruise set at 68 for most of the trip. The dash read 28.0 when we pulled into the garage. Coming from a 2011 grand cherokee hemi that just eked into 20mph on the highway, I am thrilled to see numbers like this considering how large this truck is. It's def not a drag racer but that highway passing power is incredible. My wife is not really impressed by car stuff but I even got a whoa! out of her passing a semi on a two lane road. Just under 600 miles on the odo.

Just over 11k on mine in almost 4 months. Was getting 26-28 with 60/40 highway. If just highway on a trip - would get 29-31.

just switched to 285-55-20 nitto ridge grappler tires from - lost about 3mpg.
